Hardly Strictly Bluegrass, or HSB for short (previously Strictly Bluegrass) is an annual free music festival held the first weekend of October in San Francisco's Golden Gate Park. From its outset, the festival has been subsidized by San Francisco venture capitalist Warren Hellman. The first festival was held in 2001, originally only inviting bluegrass musicians. By 2004 artists from other genres were invited and the "Hardly" was added to reflect the expanded scope.
